Highlights
- Apple plans to address iPhone 17 thermal issues by introducing vapour chamber cooling.
- New tech will be used across both Pro and non-Pro models.
- Vapour chamber cooling helps manage heat efficiently preventing processor throttling, lag and battery wear.
- Vapour chamber cooling will now be included in the entire iPhone 17 lineup.

Apple is reportedly making a big move to address thermal issues in the iPhone 17 series by introducing vapour chamber cooling across both Pro and non-Pro models.
Heat is a key factor in smartphone performance. If a device overheats, it can cause the processor to throttle, leading to slow performance, lag and even freezing. Overheating also speeds up battery wear and shortens the phone’s lifespan.
Apple’s decision to switch to vapour chamber cooling reflects its focus on improving thermal efficiency in the next generation of iPhones.
How Vapour Chamber Cooling Works?

All iPhones currently rely on traditional heat sinks made from highly conductive metals to manage heat. However, Vapour chamber cooling works differently.
Vapur champer technology uses a sealed liquid that vaporises when heated moving through a chamber to spread the heat evenly. The vapour then condenses back into liquid repeating the cycle. This system dissipates heat more efficiently while taking up minimal space and it doesn’t require extra components like fans.
The benefits of vapour chamber cooling are much more than just better heat management. This tech is crucial for maintaining performance and extending device life as processors are becoming more and more faster along with faster charging speeds.
This is especially important for the A19 Pro chipset, which is rumoured to power the iPhone 17 Pro models. Reports suggest it will reach clock speeds of up to 5GHz making effective cooling essential.
The industry expert and analyst Ming-Chi Kuo previously predicted that vapour chamber cooling would be exclusive to the iPhone 17 Pro Max due to its demanding chipset. However, more recent updates now indicate that Apple will include this technology across the entire iPhone 17 lineup.
FAQs
